Online Published on 18 October, 2023. Abstract Some biointensive IPM modules against sorghum pests explored in the present study revealed that seed treatment with imidacloprid 48%FS @ 12 ml/ kg- cypermethrin @ 2 ml/ l spray at 45 days after emergence (DAE)- treatment T5) and soil application of carbofuran 3G (25 kg/ ha) -seed treatment with chlorpyriphos 20EC @ 5 ml in 20 ml of water- spray of cypermethrin @ 2.0 ml/ l at 25DAE (treatment T5- Recommended package of practices of UAS, Dharwad) were significant and on par against shoot fly Atherigona soccata (Rondani) (13.70 and 14.59% deadhearts), aphid (Rhopalosiphum maidis (Fitch) (20.94 and 17.36 aphids/5cm2 leaf) and shoot bugs (Peregrinus maidis Ashmead) (9.77 and 10.62 shoot bugs/ plant). In case of stem borer Chilo partellus (Swinhoe) incidence was less with treatment T6: soil application of carbofuran 3G (25 kg/ ha)- seed treatment with chlorpyriphos 20EC @ 5 ml in 20 ml of water spray of cypermethrin @ 2.0 ml/ l at 25 DAE (3.43% deadhearts) followed by T1 (seed treatment with imidacloprid 48%FS @ 12 ml/ kg + intercropping with chickpea: sorghum (4:2)- NSKE (5%) spray at 45 DAE). The yields were superior with T5 and T6 (2200 and 2317 kg/ ha, respectively).
